This inventionaims to provide such machine in simple form, adapted to the re quiredvariations for production, and for high speed of operation, as well as amachine that may be used in any shop to provide small quantities ofcames having the particular characteristics of finish for a particularwindow, or for each particular set of windows that go into onestructure.

While particularly adapted to special effect of leaves on cames, invarious forms the simple mills may be used to reduce came blanks eithercast or so-called hydraulic extruded blanks,into the precise size andany shape desired by the glazer. noted that the multiple part rollsprovide for the lateral contact with the leaves to draw the came throughthe mill, and that the central. heart-engaging member may be a die orinside mandrel, or on a roller, or

may be a stationary circular part of the mill,

tion, thus providing an eflicient mill or machine for making cames inshops as desired, from the blanks of larger sizes or straightconformation.

Various arrangements of mills may be used, with some of the parts hereinshown and described, or other modifications without using the particularentire combination, and for producing a great variety of finishedproduct, without confining this invention to the specific embodimentsherein described.

Particular forms of these machines will now be described with referenceto the drawings showing particular embodiments, in which:

The machine in Figs. I to IV comprises a base 1, a frame or hearingsupport 2, with shafts 3 and-l supported in the frame or in bearingscarried thereby. Gears 5 and 6 are keyed to the shafts and engage eachother so that turning one shaft by crank 7, turns the other shaft in theoppositedirection, and in the form shown, at the same speed.

' On the other side of the frame 2 the projecting shaft ends support anumber of cooperating rolls, which at their adjacent peripheries form aclearance in H sectionof the desired size and configuration, to providefor the rolling of the came for the finishing characteristics desired.These came rollers comprise the inner d1sc 8 reglstering 1n the plane ofthe inner disc but one larger than the other so as to form a sideresisting plate for the passage of the came leaf 011 one side.

The next member of the rolls is an irregular disc 10 and irregular disc1O set flat against 8 and 9, respectively, and

has a toe 1G projecting close to the periph- I cry of the heart roll onone side, with a guiding surface 16* adapted to contact with one side ofthe heart and cooperate with the rolling contact of the heart rolls, forthe purpose of straightening the heart as it emerges from the rolls andprevent its curling. Extra plates 17'1T and 18--i8 may be used toprovide registering interengaging edges of the outside confining rolls,or the edges of the outside confining rolls may he stepped in order thata resistance against lateral pressure be provided for the rolls 8 and13, at the point where the pressure on the came tending to compress itrequires lateral resistance to prevent distortion of the leaves Wherenot desired;

The discs with irregular peripheries are in pairs 12 and 10 and 12 and10*". By having the pair on one shaft uniform as to the irregularperiphery, the resultant edges of theleaves which they engage, willsubstan-. tially register on the finished came on. one

These irregular disc rollsofthe lea-f edges arepreferably 'held by a'lzey 19 in each shaft, but enga e in one of anumber of keyways or notches, which in the figures are rihered f n i tolVith a-nuinber of setting positions, resulting from having the keyengage one or the other notch, the pair of top disc rolls will havedifferent irregularities opposed to the pair ofbottom disc roll. bysimply changing the registering of the discs on the shaft,WllEll'bllflQQillS 5 and 6 are kept in mesh in Variations of therelations .of'the disc rolls may also be accomplished by-withdrawing oneof the ears 5 7 F): ergo and-shilling it a ten: r eth. mum wil advancethe upper or iower' disc rolls with re juxtaposition of theirregularities.

will-thus be seeirthat these machines or inills serve to provide asimple device for. manipulating cames, particularly such acct to theheart as lead or other soft metahfor the purpose of. producinganyirregula-r and constantly ying relation of leaf inargins, and vari-ZtLlUIiS of the leaf surface as well. machines are simple. and maypreferably be hand operated as by the :crank indicated, but for largeproduction :may be power driven. In this art the production of specialcan'ie ,elfects and linishusually involves the treatn-ientof lengths ofblanks and of a different finish or character for different jobs, suchas set of Windows or the particular glazing for one "window, and thesemills supply in particular a compact, convenient and durable machineforthe glazers shop use. A series of sets of irregular discs, as for themachines shown in Figs. I and IV, may be kept in stock in sets oftwopairs each, and of different sizes to manipulate different sizes ofcames. The irregularities of the finish on the leaf edges may be variedby different. setting of the disc rolls on the shafts, and the assemblynd arrangement of the machine are such as to readily permit the shiftingof discs for Should it be desired to prod ce a-constantly varyingirregularity over a long strip of came, the two-gears 5 andfi may bemade of slightly different size, as, for erranngleone having one or afew teeth more than the other, the result of which will be to drive oneshaft 3 differentially faster or slower than theother'shaft' l, and aseach of irregular disc rollsis keyed to its These respective shaft, oneof the pairs will creep 1 slightly ahead of the other at eachrevolution, and for a large number of revolutions the sameirregularities on one pair will never againregistcr with theirregularities on the other pair of disc rolls. In thenor- Suchdilferentialdriving will tend also to cause the leaves on one side tocreep a little beyond those on the opposite side of the heart, which,however, will be absorbed by the d *ctility of the material, and simplys rves to increase the desired irregularities for both leaf edges andouter surfaces.

The manipulation of these mills or machines will be readily understoodfrom the aioregoing description, which consists in feeding a plain cameblank into one side of the rolls or mill, and by turning the crank therolls bite the end and draw the heart and leaves through thecross-sectional space provided, while'during its passage the engagementwith the irregular disc rolls provides the irregularities and the otherportions of the mill suitably support the ductile material in itspassage, resulting in the delivery at the other side of the mill in thefinished product with the much desired characteristics.
